        助記提示


        1. vit- "life" + -amin (原為-amine, 由于后來發(fā)現(xiàn)其中沒有氨基酸,顧將后面的字母e去掉了,其實(shí)作為物質(zhì)的代稱,現(xiàn)在加不加字母e都沒什么關(guān)系啦)。
        2. 該詞有兩種譯名,一種是意譯,即“維生素”,表示維持生命的元素,顧簡稱為維生素;另一種是音譯,即“維他命”,根據(jù)發(fā)音直譯過來的,很好理解。

        中文詞源


        vitamin 維他命,生命素

        最早寫做vitamine,來自vit-,生命,-amine,氨。后證實(shí)這種物質(zhì)不屬于氨基,因此字母e脫落。

        英文詞源


        vitamin
        vitamin: [20] Vitamins were originally vitamines: the Polish-born biochemist Casimir Funk who introduced them to the world in 1920 believed that they were amino acids and so formed the name from Latin vita ‘life’ and amine. It was soon discovered that Funk’s belief was mistaken, and alternative names were suggested, but in 1920 it was successfully proposed (by J.C. Drummond) that the -e be dropped to avoid confusion, and the form vitamin was born.
        => amine, vital
        vitamin (n.)
        1920, originally vitamine (1912) coined by Polish biochemist Casimir Funk (1884-1967), from Latin vita "life" (see vital) + amine, because they were thought to contain amino acids. The terminal -e formally was stripped off when scientists learned the true nature of the substance; -in was acceptable because it was used for neutral substances of undefined composition. The lettering system of nomenclature (Vitamin A, B, C, etc.) was introduced at the same time (1920).
